What is the relationship between the mini USB port and console port of an AR

41

Each main control board provides a console port and a mini USB port. To configure an AR, connect the serial port of the user terminal to the console port of the AR or connect the USB port of the user terminal to the mini USB port of the AR.
If a PC does not provide a console port, you can use a mini USB cable to connect a USB port on the PC to an AR's mini USB port and log in to the AR for basic configuration and management.
Note: Before logging in to an AR through the mini USB port, you need to install the mini USB port driver on a user terminal. When the mini USB port and console port are connected at the same time, you can log in to the AR only through the mini USB port.
